one of my six crossbreeds read too find out what happens

One of my freinds six crossbreed chickens he gave me when they were only about 8 days old died today. It was the door to there brooder place that had not been shut properly and it was either that he got out or the dogs got in well anyway it barely has any marks on it. They obivously tried to get at another one because one of the smaller ones neck was bloody . I am so sad it was probably one or both of our Golden Reitreiver pups but there bred for that and it's hard to get it out but there only pupys so there learn. it was one of my largest roosters named Henry I made a grave for him
and I am being extracare ful for this has me on my tiptoes.
I'll reply soon.
